Alibaba's details page can be 790, and 750 is even better. There is a section on the homepage called picture carousel, the default size is 1920 wide and 250-500 high. The custom size is 950 wide and the height is optional. These are the default sizes if you don't spend money to buy the template. If you spend money to buy the template, it's another matter.

When decorating the homepage, picture carousel and customization cannot be arranged alternately. The carousel can be set up to 5 modules, and each module can hold 5 posters. If you make the width of the customization exactly 950, it is very likely that a 1-pixel white border will appear during decoration, so I will add 2 pixels when making the width to facilitate decoration.
